Description

Technical Field

[0001] The utility model relates to the technical field of profiles, in particular to a thermal break door and window profile structure. Background Art

[0002] Door and window profiles are generally made of alloys, and thermally insulated profiles are widely used for their thermal insulation properties. Thermally insulated windows use thermally insulated bridges as both the window frame and the glass frame. Thermally insulated profiles, also known as thermally insulated thermally insulated profiles, use hard plastic to connect the broken alloys into a single piece. The "bridge" in the name "broken bridge" refers to the "cold and hot bridge" in the materials science sense, while the "break" implies action, meaning "breaking the cold and hot bridge."

[0003] The structure of thermally insulated doors and windows primarily consists of outer and inner profiles, which are connected by nylon strips. Fire-resistant glass is placed between the inner and outer profiles. The nylon strips' thermal conductivity effectively isolates heat transfer, while also providing noise reduction and insulation. However, the melting point of nylon strips is around 250°C, while the melting point of alloys is around 660°C. In the event of a fire, the nylon strips melt first, followed by the outer alloy profiles. Consequently, the fire-resistant glass loses its support and easily falls, removing the barrier that isolates the room from open flames. This exposes occupants directly to the blaze, compromising their safety and property. Furthermore, when plastic is exposed to alternating hot and cold temperatures for extended periods, the long hard plastic strips are prone to partial deformation, compromising the stability of the door and window structure.

[0004] The purpose of the utility model is to provide a thermal break door and window profile structure, which can solve the problems raised by the above-mentioned background technology in view of the shortcomings of the existing technology.

[0006] The utility model provides a thermal break door and window profile structure, comprising a first thermal break profile located on the inner side of a window frame, a second thermal break profile located on the outer side of the window frame, and a connecting piece arranged between the first thermal break profile and the second thermal break profile. A mounting groove adapted to the connecting piece is provided between the first thermal break profile and the second thermal break profile, and the cross section of the end of the connecting piece placed in the mounting groove is arched.

[0007] In some technical solutions of the present invention, there are two groups of connecting members, and the two groups of connecting members are symmetrically arranged between the first thermal break profile and the second thermal break profile.

[0008] In some technical solutions of the present invention, inclined plates are provided on the side walls of the installation groove, and an inclined surface adapted to the inclined plates is provided on the connecting piece.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention claimed, but merely represents selected embodiments of the present invention.

[0020] Embodiment 1

[0021] Please refer to Figure 1-Figure 2 as shown.

[0022] The present invention provides a structure of a broken bridge door and window profile. As Figure 1 , Figure 2 shown, the present invention provides a structure of a broken bridge door and window profile, including a first broken bridge profile 1 inside the window frame, a second broken bridge profile 2 outside the window frame, and a connecting member 3 disposed between the first broken bridge profile 1 and the second broken bridge profile 2. Installation grooves adapted to the connecting member 3 are formed between the first broken bridge profile 1 and the second broken bridge profile 2, and the cross-section of the end of the connecting member 3 placed in the installation groove is in an arched shape. The broken bridge door and window structure provided by this technical solution is divided into two parts, namely the first broken bridge profile 1 inside the window frame and the second broken bridge profile 2 outside the window frame. The structures of the first broken bridge profile 1 and the second broken bridge profile 2 are the same, and the two are symmetrically arranged only with the connecting member 3. And grooves are provided on the sides of the first broken bridge profile 1 and the second broken bridge profile 2 facing away from each other, and the grooves are located on one side of the baffle 4; used to accommodate the sealing strip to protect the glass during the later installation of the glass, avoiding hard contact between the glass and the window frame, resulting in the service life and use safety of the glass not being guaranteed. When installing the connecting member 3 between the first broken bridge profile 1 and the second broken bridge profile 2, the connecting member 3 needs to be placed at the end of the installation groove and bent into an arched shape by a machining device. The arched shape specifically includes a "C" shape, a circular spherical shape, a U shape, or a water droplet shape. After the above settings, the connecting member 3 can abut against the installation groove by the elastic force generated by the bent portion integrally formed with it, avoiding gaps between the connecting member 3 and the inner wall of the installation groove, which may affect the heat insulation and heat preservation effect of the heat insulation layer or heat insulation layer 10 formed by the cooperation of the connecting member 3 with the first broken bridge profile 1 and the second broken bridge profile 2 during actual use. The structures of the first broken bridge profile 1 and the second broken bridge profile 2 are both made of steel.

[0023] In some technical solutions of the present invention, the number of the connecting members 3 is two groups, and the two groups of connecting members 3 are symmetrically arranged between the first broken bridge profile 1 and the second broken bridge profile 2. Designing the number of the connecting members 3 to be two groups can increase the heat insulation and heat preservation effect of the heat insulation layer or heat insulation layer 10 formed by the cooperation of the first broken bridge profile 1, the second broken bridge profile 2, and the connecting member 3, and increase the connection strength between the first broken bridge profile 1 and the second broken bridge profile 2.

[0024] Furthermore, the connector 3 is made of a highly heat-resistant rubber material. In the event of a fire, even if the outer nylon plate attached to the connector 3 melts due to high temperature, the connector 3 will not melt because it is made of a highly heat-resistant rubber material. After the nylon plate melts, it will fill the installation groove. At this time, the connector will continue to fit into the installation groove, and the melted nylon plate will seal the gap between the connector and the installation groove. At this time, the pressure-stabilized structure formed by the first thermal break profile 1, the second thermal break profile 2 and the connector 3 will not fail, and the integrity of the door and window structure will also be guaranteed.

[0025] In some technical solutions of the present invention, inclined plates 8 are provided on the side walls of the mounting grooves, and the connector 3 is provided with an inclined surface adapted to the inclined plates 8. The inclined plates 8, which are provided on the mounting grooves and are integrally formed with the first thermally insulated bridge profile 1 or the second thermally insulated bridge profile 2, can lock the connector 3 within the mounting grooves, preventing the connector 3 from separating from the mounting grooves, thereby affecting the failure of the pressure-stabilizing structure formed by the first thermally insulated bridge profile 1, the second thermally insulated bridge profile 2, and the connector 3, and thus compromising the structural stability of the door or window.

[0026] In some technical solutions of the present invention, the first and second thermal break profiles 1, 2 are connected by a connector 3 to form a chamber 7, and a thermal insulation layer 10 is embedded in the chamber 7. The thermal insulation layer 10 is formed by stacking multiple layers of fireproofing and thermal insulation materials. These materials are all existing technologies and can be used in conjunction with the connector 3 to achieve fire protection, heat preservation, and thermal insulation in the chamber 7 formed by the first and second thermal break profiles 1, 2 being connected by the connector 3, thereby improving the fire protection, heat preservation, and thermal insulation effects of the device.

[0027] In some technical solutions of the present invention, a baffle 4 is provided on the top of the first thermal break profile 1. A detachable limit plate 5 connected to the second thermal break profile 2 is provided on the top of the first thermal break profile 1. A clamping plate 6 parallel to the baffle 4 is provided on the limit plate 5. Two rectangular through holes are provided on the limit plate 5, each of which is provided with a countersunk screw. Mounting holes compatible with the countersunk screws are also provided on the first thermal break profile 1 and the second thermal break profile 2. This allows for secondary fixation of the connection between the first thermal break profile 1 and the second thermal break profile 2, preventing deformation of the fixing plate 11 after a fire, which would cause the window frame structure formed by the first thermal break profile 1 and the second thermal break profile 2 to twist. The clamping plate 6 can cooperate with the baffle 4 to clamp the glass, providing stability to the window frame structure formed by the first thermal break profile 1 and the second thermal break profile 2 when the glass is installed.

[0028] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
